Turning off GDS Reclaim Processing

A system programmer can turn off GDS reclaim processing in either of two ways:

Set the value of GDS_RECLAIM in the PARMLIB member IGDSMSxx to NO, and issue the SET SMS=xx command.
Issue the SETSMS GDS_RECLAIM(NO) command.

Guideline: If GDS reclaim processing is turned off, use the access method services ALTER command to delete, rename, or roll in the generation that did not get rolled in. Otherwise, any attempt to create a new (+1) generation fails with error message IGD17358I.
